A Clockwork Orange (1971) An "ultraviolent" hooligan is convicted of his crimes and volunteers to an experimental treatment that would reduce his sentence. This film forces a little introspection. Violent nature is in all of us. "Just beneath the skin lies an animal, that wants to put his hands around your neck"- Confusion Said
My favorite Kubrick film, and definitely in my top 5 favorite films of all time.
"Welly, welly, welly, welly, welly, welly, well. To what do I owe the extreme pleasure of this surprising visit?"
